    Weed Killer

    Anyone use a mixture of vinegar and salt for killing weeds?

    I've been using 1 to 1 1/2 cups of salt per gallon of vinegar and it doesn't quite kill what I want.

    I was thinking of buying some glacial acetic acid and mixing my own vinegar but stronger than 5%.

    Good idea or should I forget about it?

    I have heard of it, never used it. Have Round up but don't use it a lot. This year I just kept picking and tossing dandelions. Most references to the salt are pretty old post war things done from chariots!

    The Romans salted the fields of Carthage to destroy their ability to grow crops for the next thousand years, so it will probably work. The highway department has done something similar to our beds near the road. I use something safe and less permanently damaging to the soil to kill weeds, like Roundup.

    Iíve been reducing my use of Round Up and now using Orthoís Weed B Gon. The Weed B Gon seems to take longer to kill (a few days to see noticeable wilt), but has been effective in eliminating most of my common lawn weeds.

    Round Up kills everything - weeds and grass. Weed B Gon only kills broadleaf weeds. Dont mix them up (DAMHIK)!

    Yes, I use a mixture of white vinegar, epsom salt and Dawn dishwashing soap...there are many recipes out there but most are pretty similar as to the ratios. I honestly just eyeball it when I'm filling and mixing in my hand sprayer. I'm just using regular white vinegar from Costco, even though sourcing higher strength would likely make for an even more effective solution. I augment using this mixture by also using a flame weeder. The combination really works well...I flame first and then hit with the spray.

    The only thing I use commercial chemical weed killer for...and that's very sparingly...is for poison ivy in certain areas. {edit} Oh, any PigWeed. But even RoundUp is challenged by PigWeed.

    Isn't Weed-B-Gone just 2,4,D? No need to pay extra for a brand name. 2,4,D is much cheaper from a farm supplier, or even Tractor Supply.

    I just used a flame weeder (Red Dragon???) for the first time, over the weekend. Lots of fun! We have a flagstone walkway area in the front yard that grows lots of weeds between the stones. The sting trimmer creates its own issues by slinging pebbles of decomposed granite all over the place and my wife is 100% anti-Roundup, so it has been an ongoing maintenance issue. Anyhow, the weed torch did a really great job. Not sure I would want to do huge areas with it but for spot weeding, I'm a believer now.

    I found that when you burn them they come back stronger.

    yes. the generics of all of them are much much cheaper at tractor supply.

    LOL, did that already. Turned around and there was a little grass fire in one of the planting beds. Had to run for the hose.

    I just sprayed (from a 1 gallon pump sprayer) Compare-n-save 2-4-d a few days ago and the weeds have started to wilt and brown pretty good. Terrible name, good cheap product just slow to kill.

    Many people make the roundup mix too strong it should take at least 48 hours to see any effect. Any sooner and you are wasting product and reducing the effectiveness. If it is too strong the plants sense it and shut down before total root kill. They will die back but the tips of the roots may survive and come back next season.
    I do not think the salt mixtures are a good idea in the west. Thousands of acres of cropland has had to be abandoned due to salt build up from irrigation in California. It is not uncommon to have drain tile in the fields to drain used irrigation water out. plants take up the water and leave the sale behind in the ground. See Kesterson reservoir for details.

    2-4-d is a plant hormone that makes them grow fast in the wrong places. that is why it takes some time. it is slow, but also more selective than most other chemicals.
